INsULAToE.

To all whom t may concern.'

Be it known that I, FERDINAND SCHAUB, a citizen of the United States,` residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and'useful` Improvements"V in Insulators, of which the following is a full, clear, and exact specification. Y

This invention relates to insulators. and has for an object to provide an improved cleat for spacing apart and i holding in proper relative positions electric wires.

The invention particularly vrelates to a cleat .made up of a pair of similar and interchangeable half-cleats, each of which contains a pair of spaced-apart wire-seats which, for convenience, may be termed half wire-seats. In the illustrated form of the invention the half-wire-seats in each halfcleat differ one from the other and each halfseat is located in position and formed for mating with the dissimilar seat in the other half-cleat when two of these are assembled.

The invention also contemplates the use in a cleat made up of a pair of cleat-inembers or half-cleats and having a pair of wire-wedging-seats, each o f which half{ cleats will have a wire-seat and an adjacent wedge, and a wire-seat and anadjacent` Y at one end (the end carrying the seat 14),

cleat or the bottom of the lower cleat. Fig.

3 is a plan view of the meeting face of one of the half-cleats. Fig. 4 is a similar view with the ends reversed and showing the relation in which the cleats will assemble one with the other. Fig. 5 is an elevation of one of the half-cleats. Fig 6 is a longitudinal view of a pair of assembled half-cleats held in position on some suitable support by means of screws; and Fig. 7 is a cross-sectional view taken at about the plane indicated by the line 7-7 of Fig. 1.

Since the invention contemplates the use of a pair of half-cleats similar in form and interchangeable7 one of these cleats by itself Vthe seat 11).

will first be described. The'cleat illustrated comprises an elongated body portion 10, made, for instance,,of'porcelaim and having at each end a half-wire-seat. At one end it is provided with a seat 11, having a concave surface, this seat curvingl inward relatively to the body and outward relatively to the end, and lying wholly within the edges of the meeting face of the body. Adjacent the half-wire-seat 11, is. shown a boss 12, provided with a wedge-face 13, which merges into the wall lof the wire-seat 11. At the other end of the body is a wire-seat l-l, which curves outward relatively to the end and outward in the center relatively to the body, the surface of this seat being' conveX. This wire-seat passes through the sideface 15, of the cleat body. The fianges 110 at the ends of the seat 11, serve to pass the wire into the portions of the seat 14, at thethan it is at the other' end (the end vcarrying Then the half-cleats are assembled they interlock in such manner that independent movement on the plane of cleavage is prevented.

The cleat is provided with a 'pair of holes 17, through which screws will be passed for holding a pair oftheSe cleat-halves in assembled position. Suitable screws 18, are illustrated in Fig. 6, which will hold the halves together and against some suitable surface. The boss 12 will. be accommodated by a socket 19, adjacent the seat 14, which socket may for convenience be termed a wedge-seat. The screw-holes in the present instance are shown passing respectively through the center of the boss 12 and the socket 19. The screw-holes are counter-sunk. Adjacent the counter-sinking is a raised ring or Hange 20 which will hold the body portion of the cleat from surface engage-` 'ment with the surface upon which the cleat is mounted for preventing breakage when the screws are tightened. i/Vhen the cleathalves are assembled, the wire-seat (which may be termed a half-seat .11), will @0615er ioo ate with the wire-seat la (which may be termed a half-seat) in another cleat member, and thereby form a wire-seat so that a complete wire-seat will be formed at each end of the cleat by the mating of a pair of dissimilar' wire-seats or half-seats. Each halfcleat is so formed that it will interchangeably mate with a similarly formed cleat, but only in one certain relative position. The dissimilar ends must be together. The pair of cleat members will then mate and form a pair of similar, spaced-apart wire-seats.

In Stringing the wire, the wires will be placed preferably in the seats lil, the cleats assembled, and by means of the Wedging action of the wedge-faces I3, and the coniiguratin of the seats ll and I4 the wires will be bent in both a vertical and a horizontal plane resulting in a compound bend, which will produce a kink for preventing the wire from reeving through the wireseats. Owing to the bending of the wire in the seats, in the present instance the double kinking of the wire, the pressure required to prevent its reeving is less than in existing forms of clea s, so that the strain on the porcelains is greatly lessened and they may be held together by a comparatively slight pressure of theA screws 17. This being the case, the breakage in Yinstalling' and in the use of the cleats is minimized.

Although but one practicable embodiment of my invention is illustrated and in that embodiment a pair of seats is shown, it will be apparent that changes may be made within the scope of the claims without departA ing from the spirit of my invention.

Having thus described my invention, I,

claim: v

1. An insulator, comprising a pair of complemental elongated sections, each formed with a pair of spaced-apart curved wire-receiving grooves and a tapered centering and expanding plug positioned adjacent one of-said grooves and having a curved wire-engaging surface concentric therewith, and a complemental countersink adjacentJ the other of said grooves to receive the tapered xpanding plug of the ad- Gopies of this patent may be obtainedrf jacent section, each groove and cooperating expanding plug co-acting to kink and clamp a wire with a wedging action in a direction at right angles to the axis of the plug and in a plane parallel thereto.

2. An insulator, comprising a pair of complemental elongated sections, each formed with a pair of spaced-apart curved wire-receiving grooves and a tapered centering and expanding plug positioned adjacent one of said grooves and having a curved wire-engaging surface concentric therewith, and a complemental countersink 'adjacent the other of said grooves to receive the tapered expanding plug of the adjacent section, each groove and cooperating expanding plug coacting to kink and clamp a wire with a wedging action in a direction at right angles to the axis of the plug and in a plane parallel thereto, the registry of said expanding plugs and countersinks preventing individual movement of the sections at the plane of cleavage. y

3. An insulator, comprising a pair of complemental elongated sections, each formed with a pair of spaced-apart curved wirereceiving grooves, and a bored tapered centering and expanding plug positioned adjacent one of said grooves and having a curved wire-engaging surface concentric therewith, and a complemental board countersink adjacent the other of said vgrooves to receive the tapered expanding plug of the adjacent section, and a securing screw positioned in the bores formed within said plugs and countersinks whereby each groove and cooperating expanding plug will coact to kink and clamp a wire with a wedging action in a direction at right angles to the axis of the plug and in a planeJ parallel thereto upon the seating of Said screws in a suitable support.

In witness whereof I have Vhereunto set my hand in the presence of two subscribing witnesses.
